Ubuntu: New Tomcat packages fix security vulnerabilities

It was discovered that the Tomcat SecurityManager did not properly restrict the working directory. An attacker could use this flaw to read or write files outside of the intended working directory. It was discovered that Tomcat did not properly escape certain parameters in the Manager application which could result in browsers becoming vulnerable to cross-site scripting attacks when processing the output. It was discovered that Tomcat incorrectly enforced the maxHttpHeaderSize limit in certain configurations. A remote attacker could use this flaw to cause Tomcat to consume all available memory, resulting in a denial of service. Updated packages are available from security.ubuntu.com.

===========================================================
Ubuntu Security Notice USN-1097-1 March 29, 2011
tomcat6 vulnerabilities
CVE-2010-3718, CVE-2011-0013, CVE-2011-0534
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 9.10
Ubuntu 10.04 LTS
Ubuntu 10.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 9.10:
libtomcat6-java 6.0.20-2ubuntu2.4
tomcat6-admin 6.0.20-2ubuntu2.4

Ubuntu 10.04 LTS:
libtomcat6-java 6.0.24-2ubuntu1.7
tomcat6-admin 6.0.24-2ubuntu1.7

Ubuntu 10.10:
libtomcat6-java 6.0.28-2ubuntu1.2
tomcat6-admin 6.0.28-2ubuntu1.2

In general, a standard system update will make all the necessary changes.

Details follow:

It was discovered that the Tomcat SecurityManager did not properly restrict
the working directory. An attacker could use this flaw to read or write
files outside of the intended working directory. (CVE-2010-3718)

It was discovered that Tomcat did not properly escape certain parameters in
the Manager application which could result in browsers becoming vulnerable
to cross-site scripting attacks when processing the output. With cross-site
scripting vulnerabilities, if a user were tricked into viewing server
output during a crafted server request, a remote attacker could exploit
this to modify the contents, or steal confidential data (such as
passwords), within the same domain. (CVE-2011-0013)

It was discovered that Tomcat incorrectly enforced the maxHttpHeaderSize
limit in certain configurations. A remote attacker could use this flaw to
cause Tomcat to consume all available memory, resulting in a denial of
service. (CVE-2011-0534)
